Black-Leg In Cattle, F C. Wilkinson

Journal of the Department of Agriculture, Western Australia, Series 4

BLACK-LEG is still a serious disease of cattle in the South West coastal region, causing deaths in young cattle.

The disease is characterised by hot swollen muscles, acute lameness and rapid death.

Cattle affected are usually 6 to 12 months old, in fat condition, and grazing on lush pastures.

Journal of the Department of Agriculture, Western Australia, Series 4

Can mastitis be eliminated from a dairy herd? The results of a 12-month continuous study of four commercial herds show that it could be done.

Shed Lambing In The Esperance Environment, T Marshall, F. F. Dixon

Journal of the Department of Agriculture, Western Australia, Series 4

Neonatal lamb mortality is often high in Western Australia and losses as high as 33 per cent, have been recorded on private properties in the Esperance area. Surveys by Western Australian Department of Agriculture officers have indicated that more than threequarters of such lamb deaths occur after birth. About half these deaths result from the combined effects of weather and mismothering.

Work in Victoria has indicated that lamb mortality may be reduced by intensive lambing systems such as shedding and this trial was established to see if shedding could reduce lamb mortality in the Esperance environment.

Are Bactericides Necessary In Sheep Dips?, M R. Gardiner

Journal of the Department of Agriculture, Western Australia, Series 4

THE OCCURRANCE of mycotic dermatitis in sheep in Western Australia, although rather unpredictable, is quite frequent throughout the higher rainfall districts.

Efforts have been made for several years to control infection by adding bactericides to dips.

Eye Cancer In Cattle, E P. Meyer

Journal of the Department of Agriculture, Western Australia, Series 4

Swine Fever And African Swine Fever, V W. Smith

Journal of the Department of Agriculture, Western Australia, Series 4

PIGS may become infected by viruses which also cause disease in other animals (for instance foot-and-mouth disease) but there are two virus diseases worthy of special mention because they cause clinical disease in pigs only.

Practical Disease Prevention In The Pig Herd, R B. Richards

Journal of the Department of Agriculture, Western Australia, Series 4

DISEASES cause loss in pig production through mortality, poor growth rate and reduced food conversion efficiency.

The cost of drugs and expert advice causes further economic loss, and the dangers to public health and to other livestock in a community are serious and often-neglected considerations.

Pig Husbandry Research In Western Australia, N W. Godfrey

Journal of the Department of Agriculture, Western Australia, Series 4

IN the past it has not been possible to undertake research work with pigs on any appreciable scale in Western Australia.

A small herd has been maintained at Denmark Research Station for some years as a demonstration side-line unit, run in conjunction with the dairy herd.

A number of very useful trials have been carried out with the Denmark herd, but its size has limited the comprehensiveness of the type of research work that could be undertaken.

Sheep Drenching Programms, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

Drenching of sheep to prevent build-up of worm infestations is commonly practised on many properties in the agricultural districts of Western Australia. This is called strategic drenching.

Sheep Worm Control And Lambing Time In High Rainfall Areas, F C. Wilkinson

Journal of the Department of Agriculture, Western Australia, Series 4

Indications from a continuing sheep trial at Margaret River are that farmers in high rainfall areas could increase stocking rates and lamb growth rates by lambing in September- October rather than July-August.

The results also indicate that farmers in the area may be spending more than necessary on worm control.

THIS article deals with five species of the genus Gastrolobium. The plants look rather similar so in the past have often been confused. They occur over a considerable area of the agricultural region of Western Australia.

Bovine Tuberculosis Control In Western Australia : Past, Present And Future, M R. Gardiner

Journal of the Department of Agriculture, Western Australia, Series 4

TWENTY YEARS AGO, tuberculosis was a widespread and serious disease in the dairy cattle of Western Australia.

Besides having a marked depressing effect on the economy of the dairying industry, bovine tuberculosis was a constant hazard to humans coming in contact with it.

Journal of the Department of Agriculture, Western Australia, Series 4

THERE is a wide variation in the efficiency and cost of drugs for worm control in sheep.

Generally, the higher the efficiency, the greater the cost. Prices are subject to change, and may vary with the amount of drench purchased.

Journal of the Department of Agriculture, Western Australia, Series 4

Progress report of a study of lamb losses in experimental flocks on Department of Agriculture research stations in the agricultural areas.

THE major barrier to increased production by the West Australian sheep and wool industry is the shortage of sheep in the agricultural areas of the State, and much research has been directed towards overcoming this shortage.

Mastitis In Western Australian Dairy Cattle, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

IN 1964/65, as a first step towards a State-wide mastitis control programme, the Department of Agriculture undertook a survey of mastitis in West Australian dairy herds.

The survey was designed to obtain a clear picture of the incidence and severity of the disease and is the most comprehensive mastitis survey carried out in Australia.

Bluetongue Of Sheep, M R. Gardiner

Journal of the Department of Agriculture, Western Australia, Series 4

BLUETONGUE is a serious disease of sheep, mainly of introduced European breeds, throughout the African continent.

It is maintained there by wild and domestic ruminants in the presence of certain insect vectors (carriers).

The disease has probably existed there from immemorial times among the indigenous ruminants, emerging as a recognised disease only when the much more susceptible European breeds were brought into the continent.

West Midlands Development : Poison Plants In The West Midlands, T E H Aplin

Journal of the Department of Agriculture, Western Australia, Series 4

TOXIC plants have caused considerable economic loss to stock raisers since the early days of settlement in Western Australia.

Although much is now known of the toxic materials contained in such plants, and although most of the plants have been thoroughly publicised, losses are still occurring in many areas.

Amsinckia Or Yellow Burr-Weed (Amsinckia Spp.), G R W Meadly

Journal of the Department of Agriculture, Western Australia, Series 4

YELLOW BURR-WEED is widely established in the Wimmera and Mallee districts in Victoria, presumably introduced with fodder brought to this country from the United States about 1914.

It is a problem in Oregon and other north west wheat areas of America.

The weed is also widespread in New South Wales, being most troublesome in the wheat-growing sections of the Riverina. It is not established to the same extent in South Australia and Queensland.

The recent discovery of areas infested with yellow burr-weed at Merredin prompted the Agriculture Protection Board to declare it a primary noxious weed for Western Australia.
